Pluteus aurantiorugosus photo and description

The current name is Pluteus aurantiorugosus (Trog) Sacc.

The etymology of the name is from the Latin pluteus, im and pluteum, in 1) a movable canopy for protection; 2) immovable defensive wall, parapet and aurantiacus (lat.) – orange, orange, + rugosus (lat.) – wrinkled, folded.

head небольшая диаметром около 2-5 см выпукло-колокольчатая с подогнутым краем в молодости, затем при созревании становится выпуклой, плоско-выпуклой, иногда сохраняя слабовыраженный бугорок, негигрофанная. Даже у созревших грибов шляпка не становится плоской, вогнутой.

В окраске шляпки преобладают желто-оранжевые, оранжевые, оранжево-красноватые тона с тенденцией выцветания к краю. Центр, как правило, окрашен ярче — вплоть до ярко-алого цвета. Поверхность вначале гладкая блестящая с ровным краем, с возрастом приобретает шероховатую зернистость, похожую на мелкие жилки и складки, по мере созревания складчатость становится более очевидной (впрочем, этот признак может быть слабо выражен, или и вовсе отсутствовать).

Leg central (sometimes may be slightly eccentric) 3 to 8 cm long and 0,5 to 1 cm wide, cylindrical with a slight thickening towards the base, often curved, slightly pubescent and fibrous. The color of the stem at the cap is whitish, along the entire length it is yellowish, at the base it is often a darker shade with orange-reddish fibers.

leg pulp yellow in color and rather loose and fragile.

The orange-wrinkled whip grows on stumps, dead wood, or on the trunks of various broad-leaved trees that have fallen to the ground, preferring poplar, alder, elm, ash and maple. The literature describes rare isolated cases of fungus finds on pine trees. The distribution area is quite extensive, it is found in the countries of the Northern Hemisphere, although quite rarely. Grows singly and in small groups. Fruiting season: summer and autumn.

There is no information about toxicity, but the mushroom is considered inedible due to its rarity, small size and lack of taste.

It is similar to some species of the genus of whips that have a yellow color.
